Almost all radio stations are full of toxic music even the Country stations.
The radio itself is on 440hz frequency to irritate the masses and have us fight each other.
The low vibes that come from the music is because the writers of the music have evil intentions. They even run a Satanic ritual on the song which must be bad in some way or another.
The music fills the air of the room and vibrates in a negative way which vibrates the water in your body and makes you feel what the music's vibes are. This means the negative vibe music lowers our vibe towards fear which is the worst end of the emotional spectrum. Even if the songs sound innocent, I assure you, if it's coming out of the radio, or TV, it's usually always bad.
The highest vibe is pure silence. Pure silence lifts People's vibes by forcing them to release inner traumas which heals the mind. This is why meditation works so well.
The things inserted into songs are typically done by the producers and not the artist. Producers change the music quite a bit from what is initially recorded. Back when CDs were sold in stores, you would hear an easily recognized tone stimulus right before the album's name was sung in a song (usually a title track and played heavily on the radio). These tones were subtlety inserted but you could pick it up if you knew what to listen for.
I don't doubt this but do you have any examples of this "tone stimulus?"
In the 90's it was usually a Nokia incoming call tone. I don't recall the exact songs, but try listening to title tracks from that era
